Selecting the Edges of an Extrusion in an Assembly

Hello

I'm asking you because I'm stuck on a part of part of parameterization of parts.

Indeed, I was able to put an equality constraint between the sketches or rather the x and y sides of a sketch of a part with the x and y dimensions of the extrusion of another part but I can't constrain the edge of an extrusion (carre_troué) with the edge of the removal of material from another piece (carre_vert). The selection does not let me choose the 2. When I click on one, I can't select the 2nd one (by holding the ctrl key).

In summary, I would like to put an equality constraint between 2 edges of 2 different functions (extrusion and material removal) so that when I change the thickness (extrusion) of the green square, the hole of the large square which has the same dimensions as the green square can also change and take the same dimension. The equality constraint between the x and y sides is not a problem for me, but the thickness is the thickness.

Here are photos of the assembly. 

I'm going to put my 2 pieces and the assembly as an attachment so that you have an idea of the problem.

If someone could clarify this issue for me please, I will be very grateful.

 

Thank you.

Kind regards

David.

Here is the "carre_troué" piece .

And here is the "carre_vert" piece.

Thank you.

You have to set the extrusion depth of the green square to "to the top" or "to the surface" and select the bottom of the square hole of the other part.

Thank you very much.

I'll try that as soon as possible.
